Unexplained Subfertility

In 20% of couples we will not find any problems in ovulation, sperm quality or numbers, or tubal patency. This is called unexplained infertility.

This is generally reassuring as normal conception is very likely. However if you are not pregnant after two years, treatment options can be discussed depending on the age of the female partner and duration of infertility.

Treatment options include intrauterine insemination in natural or hormonally stimulated cycles, or IVF. In this situation IVF is both a diagnostic test and a treatment, as it may reveal subtle factors contributing to the delay in conception which have not been picked up in routine tests.
